The typical shotgun is a 12-Gauge, which is pretty large in bore diameter compared to any pistol or rifle you'll see commonly, now consider that there's two of those big barrels next to each other.

Looking at the pump shotgun, you have the same bore diameter, and then the tube underneath the barrel is the magazine, so they have to fit the entire shotgun shell in there, meaning the magazine will typically be of a very similar outward diameter as the barrel.
Boomstix are just big.
